An object of my struction of va traffic signal forfmotor' vehicles of the semaphore type adapted to be attached directlyy to the framework ofla" ve'- '.hicle, .preferably of the closed type, thearm being actuated by a handle inside the can l Another obj ect of my invention is to' con! Astruct the signal device of apair of discs one being fixed 'in positionand the othe r'frotary';` one of the discs also having a series of contact points and the otherdischaving a single Contact adapted to be connected toa jf :groiind whereby on swinging 4of the semaphorefarm a contact is made lthrogh anyone of the contact points and hence gives a lighted signal 'i for the dierent signalingpositions of the 'semaphore arm..

A semaphore arinis attached to the movable-disc and .carries 4a sleeve being adapted to pass with complementary grooves and. in `the groove of the moving plate there .i s posian electrical .conducting metal se-ginent with two insulating/strips on each side insnlating the conducting'segment from the A bolt is passed through the disc and through the strips, being in" .sulated from the disc by having a conducting contact with the metal segment. Preferably three such bolts are used, vthe heads of said bolts forming Contact points to be engaged by a slidable contact spring secured directly in the groove of the opposing disc. 'The electric wires lead from the battery or `source of power to the semaphore arm through same to the lamp. The return circuit from the lamp is to one of the bolts and from the contact point formed bythe headofthe bolt through the sliding contact to the ground and hence returned to the battery.
